IMPROVEMENT IN FROST-PROTECTOR FOR POSTS.

The Schedule referred to in these Letters Patent and making part of the name.

To all whom it ma/ z/ concern:

Be it known that I, SAMUEL T. VARIAN, of Plain field, Union county, New Jersey, have invented a nev and do hereby declare that the' following is a full, clear, and

exact description thereof,which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.

The present invention relates to a new and useful device for the protection and prevention oi' the e'ects of frost .on the supports of piazzas and buildings, gate-v or fence-posts, the effect, ofthe frost being received on a sliding tube or cylinder itted over the main support, the construction and operation of which will be understood from the following description. Y

The drawing represents a sectional elevation of a supporting-column of a piazza with my post-protector attached.

The letter A represents a metal column, set on a pedestal, B, at such a depth below the surface of the ground as not to be affected by the frost.

Thenan outer case or cylinder, C, is slipped over the said column loosely, the same being capped with a suitable stufing-box, D, so as to prevent water from running into the cylinder and freezing it to the column.

It will thus be seen that the action of the frost against the cylinder C will have no effect on the column supporting the piazza, for as the frost heaves up the ground around the supports, it will simply cause the cylinder C to slide up the supporting-columns and leave them unmoved.'

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The outer case or cylinder G, as applied to the supports of piazzas and buildings, gate or fence-posts, in the manner and for the purpose substantially as herein shown and described.
